A sleep study is a medical test performed while the patient sleeps and is used to evaluate and diagnose a sleep disorder. Sleep studies are safe, noninvasive procedures that provide valuable information. Sleep studies are outpatient tests done in a private room with a television. The process will begin with some paperwork and a health questionnaire that aid in diagnosis and treatment.
Before the sleep study begins, the sleep technician will apply several monitors to the body that record information when you sleep. The setup includes 22 sensors applied to the head, face, shoulders, chest and legs to record brain activity, breathing, heart rate, blood-oxygen levels and chin, eye and leg movements.
Results of the sleep study will be reviewed with the patient by a sleep specialist or referring physician.
